Abstract

L'invention concerne un dispositif de serrage magnétique pourvu d'au moins une unité de retenue magnétique qui comprend un aimant commutable générant une force de serrage magnétique au niveau d'une pièce et un organe de détection. Cet organe de détection comprend une bobine exploratrice conçue pour produire un signal de détection signalant la présence d'un flux magnétique afin de déterminer au moins de manière approximative une force de serrage exercée sur la pièce à serrer. L'invention concerne également un procédé permettant de détecter un état de fonctionnement d'un dispositif de serrage magnétique.
